All degree-based trigonometric functions (sind, cosd, tand, cotd, secd, cscd) and their
inverses (asind, acosd, atand, acotd, asecd, acscd) display significantly enhanced
performance.

Compatibility
Considerations
bessel Warns besselj Replace all instances
of bessel with
besselj.
erfcore Errors erf, erfc, erfcx,
erfinv, or erfcinv
See the function
reference pages
for the individual
functions.
intwarning Errors None Remove all instances
of intwarning from
your code.
optimset Errors for Optimization Toolbox Options
If you do not have an Optimization Toolbox™ license, and you set an optimset option
for a solver that is only available in Optimization Toolbox, optimset errors. Previously,
optimset would warn, not error, and ignore the option.
Compatibility Considerations
Change your code to set only those options that apply to your solver: fminbnd,
fminsearch, fzero, or lsqnonneg.
atan Warning Being Removed
When you use atan(1i) and atan(-1i) you no longer get a warning.
Compatibility Considerations
Remove instances of the warning ID MATLAB:atan:singularity from your code.
